Abstract des Autors

Acromioclavicular dislocation is a rather common injury in sports practice, particularly in contact sports (American football, soccer, basket) and those which cause falls with possible direct or indirect shoulder trauma (motor sports, horse riding, skiing). Various methods of treatment are proposed in literature. Some are addressed to anatomical reconstruction (synthesis, syndesmopexis), while other techniques, like tangential clavicular resection, derive from the concept that an anatomical reconstruction is not necessary for functional recovery and have as their main goal an aesthetic result. Thirty professional (7 cases) or amateur (23 cases) athletes were treated for acute (22) or chronic (8) acromioclavicular dislocation, most of them by tangential clavicular resection. The clinical-radiographical results were excellent or good in 26 cases (87%). Only in three athletes, treated with different surgical techniques (syndesmopexis, synthesis and tangential clavicular resection) the sport performance recovery was uncomplete. No significant difference was found between acute and chronic lesions. Complications were represented by recurrence in 1 case, infection in 1 and bridging ossifications in 4. Although definitive conclusions cannot be drawn due to the small number of cases in each group, it is evident that also in sportsmen the tangential clavicular resection is a valuable technique, with low risk of complications, especially for chronic lesions.
